 The input doesn't look consistent to me. Is Dir supposed to be an
optional value? If that is the only optional, it can be worked
around. But if the missing direction (I'm guessing) is due to
malformed input data, you have a hell of a job in front of you.

 What do you want to do with incomplete or malformed data? Try to
parse it as a "best effort", or simply spew out an error message for
an operator to look at?

 In the latter case, I suggest a stepwise approach:

* Split input by ',' ->res0

* Split the first result by ' ' -> res

-> Id = res[0]
-> Address = res[1:]
-> StreetNum = res[1]
-> StreetName= res [2:]
-> SufType = res[-1]

* Check if res0[1] looks like a cardinal direction
 If so Dir = res0[1]
 Otherwise, croak or use the default direction. Insert an element in
 the list, so the remainder is shifted to match the following steps.

-> City = res0[2]

* Split res0[3] by ' ' -> respp

respp[0] -> Province
respp[1:] -> Postcode


 And put in som basic sanitation of the resulting values, before
committing them as a parsed result. Provinces and post codes, should
be easy enough to validate against a fixed list.
